摘要:

为解决硫铝酸盐水泥基注浆材料(SCGM)放热快、凝结硬化时间不稳定、成本相对较高等问题,以及进一步促进机制砂石粉资源化利用和绿色建材发展,本文研究了石粉对SCGM流动性、泌水率、凝结时间和抗压强度等性能的影响,并通过XRD、SEM、TG-DTG、NMR等微观测试手段探究石粉对SCGM工作性能的影响机理。结果表明:石粉可以促进SCGM的水化,提高28 d力学性能,填充材料空隙;当石粉掺量为5%(质量分数)时,SCGM试样与未掺石粉试样相比,3 d强度下降11.4%,28 d强度上升10.5%,孔隙率下降10.3%;此外石粉可改善SCGM流动性,延长凝结时间。

Abstract:

To address the issues of rapid heat release, unstable setting and hardening time, and relatively high cost in sulfoaluminate cement-based grouting material (SCGM), and to further promote the resource utilization of manufactured sand stone powder and the development of green building materials, this study investigated the effect of stone powder on the fluidity, bleeding rate, setting time, and compressive strength of SCGM. The underlying mechanism of stone powder on the workability of SCGM was explored using micro-testing techniques such as XRD, SEM, TG-DTG, and NMR. The results indicate that stone powder promotes the hydration of SCGM, enhances its 28 d mechanical properties, and fills material voids. When the stone powder content is 5%(mass fraction), compared with the reference sample without stone powder, the 3 d compressive strength of SCGM decreases by 11.4%, while the 28 d compressive strength increases by 10.5%, and the porosity decreases by 10.3%. Additionally, stone powder improves the fluidity of SCGM and extends its setting time.
